…I think the defensive aspect of their game improves but the thing I most like is converting wingers to play FB.
it’s nothing new, the greatest I’ve seen at Everton was Ray Wilson who started out as a winger. Tommy Wright was an attacker & John Hurst a central striker in an FA Youth Cup winning team. Even Tony Hibbert was a defensive midfielder in an FA Youth Cup winning team.
Having that background does naturally help defend in one-on-ones but most importantly they have athleticism and real quality in possession. Mills has a bit of his Dads mentality, he has a chance of a career in the game.
Most lads at Academy level, who play in defence, have started off in other positions.
Usually due to them losing a bit of pace, when they hit puberty and they bulk up / body changes shape.
